A systemic meta-analysis has shown that statin users had a significantly reduced risk of colorectal cancer. The study included patients with and without inflammatory bowel disease, which is associated with an increased risk of this type of cancer. The largest chemopreventive effect was observed in patients with this gastrointestinal disorder, according to Kevin Singh, MD, who presented the findings during the virtual edition of the American College of Gastroenterology 2020 Annual Scientific Meeting.
Independent of smoking status, variation in EGFR and KRAS mutation frequency in Latin American patients with lung cancer was associated with Native American ancestry, according to a research brief published by Carrot-Zhang et al in Cancer Discovery. The findings of the genomic and ancestry analysis may suggest prevention and early detection strategies for lung cancer in Latin America and in other countries, especially for nonsmokers.
A study published by Michael S. Leapman, MD, and colleagues in JAMA Oncology found substantial regional variation in the use of genomic testing for prostate cancer, raising questions about access and other factors that might promote rapid adoption of new cancer technologies.
